[0030] Specifically, the reinforcement layer 6 has a lattice-shaped cross section, and is disposed between the corrugated box outer box body 1 and the inner box body 7. The advantage is that the reinforcement layer 6 with a lattice-shaped cross section is provided, which improves the structural strength of the corrugated box, is not easily deformed, and is more durable.

[0031] Specifically, the vent hole 1 3 and the vent hole 2 8 both correspond to the center of the grid of the reinforcement layer 6, and the height of the vent hole 1 3 is lower than the height of the corresponding vent hole 2 8. The advantage is that the vent hole 1 3 and the vent hole 2 8 both correspond to the center of the grid of the reinforcement layer 6, which does not affect the structural strength of the structural carton, and the height of the vent hole 1 3 is lower than the height of the corresponding vent hole 2 8. When the outer wall of the carton contacts rainwater, water can only flow into the vent hole 1 3, and will not flow into the interior of the inner box body 7 from the vent hole 2 8, so that the air permeability is maintained while having a waterproof effect.

[0032] Specifically, the cross section of the ventilation rack 11 is a repeatedly arranged "J"-shaped structure, and the handle hole 1 4 and the handle hole 2 9 are both adapted to the handle cover 5. The advantage is that the ventilation rack 11 is provided, and the airflow enters the interior of the carton from the air hole 1 3 and the air hole 2 8, flows through the air duct formed by the ventilation rack 11, and the articles are placed on the ventilation rack 11, and the airflow can flow through the lower end of the articles, thereby improving the ventilation effect.

[0033] Embodiment 2: Figure 2-6 As shown, as an improvement to the previous embodiment.

[0034] Specifically, the partition assembly 12 includes a frame 1201, a bracket 1202, a top plate 1203, a square hole 1204 and a handle 1205. The lower end of the frame 1201 is provided with the bracket 1202, the upper end of the frame 1201 is fixedly connected with the top plate 1203, and the upper end of the top plate 1203 is provided with a square hole 1204.

The advantage is that the four partition frame assemblies 12 are stacked up and down to divide the space in the carton, thereby improving the space utilization rate.

[0037] Working principle: When in use, the reinforcement layer 6 with a grid-like cross-section improves the structural strength of the corrugated paperboard box, making the corrugated paperboard box less likely to deform. The air vent 1 3 and the air vent 2 8 correspond to the center of the grid of the reinforcement layer 6, and do not affect the structural strength of the structural paperboard box. The height of the air vent 1 3 is lower than the height of the corresponding air vent 2 8. When the outer wall of the paperboard box contacts rainwater, water can only flow into the air vent 1 3, and will not flow into the interior of the inner box body 7 from the air vent 2 8, maintaining air permeability while having a waterproof effect. When items are placed on the ventilation rack 11, airflow enters the interior of the paperboard box from the air vent 1 3 and the air vent 2 8, and flows through the air duct formed by the ventilation rack 11. The airflow can flow through the lower end of the item to improve the ventilation effect. The four partition frame components 12 are stacked up and down to divide the space inside the paperboard box and improve space utilization.
